BTEC's are more vocational and practical qualifications have a different way of being marked/moderated to A levels and GCSE's usually. That's because they generally are structured and assessed differently to A levels and GCSE's.
No one knows yet. But BTEC's generally even before Covid had a higher percentage of candidates getting A* and A equivalent grades (DS & DS*), than A level and GCSE students did.
You'll just have to wait and see.
